In Swaziland and the eastern Transvaal it is usually found along the edges of streams and in marshy places. In localities of high rainfall, such as Haenertsberg on the Drakensbergen in the Transvaal, this plant is often a conspicuous and beautiful object on the grassy slopes facing east. It flowers during January and February. As soon as the seed has set, a few months later, the leaves wither almost completely to their bases, leaving a short stem surrounded by a few dried leaves to weather the winter drought. We are indebted to Mr. Chas. Maggs of Pretoria for the specimen figured in our illustration. It was collected by Mr. Maggs on his Waterval Estate, near Sabie, on the Drakensberg, in January 1921, and forwarded to the Division of Botany, where it flowered in January the following year. _Aloe microcantha_ was first collected by Bowie and introduced into cultivation in 1819. It was figured in Curtis’ _Botanical Magazine_ in 1821 as a plant of great rarity from the Cape of Good Hope.
